2-2-2. Design of Land Pattern
(1) Recommended land dimensions are shown below for proper amount of solder to prevent cracking at the
time of excessive stress to the Capacitors due to increased amount of solder.
{ Recommended land dimensions (Ex.) }
[ For High Capacitance, General Electronic Equipment, Low ProfileType, 100V･200V series,
630V series, High-Q Capacitors ]

(2) The size of lands shall be designed to be equal between the right and left sides. If the amount of solder on
the right land is different from that on the left land, the component may be cracked by stress to one side of
the component since the side with a larger amount of solder solidifies later at the time of cooling.
